0.35pitch 8Layer HDI PCBs for Burn in boards and semiconductor Test boards / thin board
Burn-in is a process done to components prior to regular use in which the components are stressed to detect failure and ensure component reliability.
The PCB burn-in process is usually done at 125ºC, with electrical excitation applied to the samples. The process is facilitated by using burn-in boards where the samples are loaded. These boards are then inserted into the burn-in oven which supplies the necessary voltages to the samples while maintaining the oven temperature at 125ºC. The electrical bias applied may either be static or dynamic.
1 . Descriptions:
What is a BIB ?
A burn-in board is a printed circuit board that is used in the burn-in process. The components added to the board are stressed using extreme heat to highlight any failures. Once the stress tests have been completed engineers will analyse the results to make sure everything is working within the correct parameters.
